For a person with normal kidney function, the plasma elimination half-life of most gadolinium-based contrast agents is approximately 1.5 hours. Understanding how long does it take for gadolinium to get out of your system is crucial for patients undergoing contrast-enhanced MRI procedures, as clearance depends heavily on individual health and the type of agent used.
